From d45d97873b8e4a005701bdbc3d916f368f95bc60 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 11 Nov 2021 10:15:44 +0000 Subject: [PATCH] media: atomisp-ov2680: implement enum frame intervals Allow the sensor to report the per-resolution frame interval. It should be noticed that, despite the ov2680 datasheet says that, for resolutions <= 1280x720, the sensor supports 60fps, the data at ov2680.h tells otherwise, limiting it to 30fps. Not sure yet if this is a limitation of atomisp or if it is just because the tables are incorrect.
